[Verse 1]
Like that time when sudden drops
Falling into your eyes
I won't let your smile fade into the past
You're my moment of happiness
[Verse 2]
You're my shine that only shines
Fallin' into my heart
Don't know how to stop, don't know why
You make my life full of happiness
[Refrain]
Du-ru-ru-ru
Du-ru-ru-ru-ru-ru-ru
Du-ru-ru-ru-ru
Du-ru-ru-ru-ru
[Chorus]
'Cause your touch soothes my mind
You make my heart keep beating
You're the light of my life
All I ever want is you
(Du-ru-ru-ru)
[Verse 2]
You're my shine that only shines
Fallin' into my heart
Don't know how to stop, don't know why
You make my life full of happiness
[Refrain]
Du-ru-ru-ru
Du-ru-ru-ru-ru-ru-ru
Du-ru-ru-ru-ru
Du-ru-ru-ru-ru
[Chorus]
'Cause your touch soothes my mind
You make my heart keep beating
You're the light of my life
All I ever want is you
(Du-ru-ru-ru)
[Verse 2]
You're my shine that only shines
Fallin' into my heart
Don't know how to stop, don't know why
You make my life full of happiness
[Outro]
Du-ru-ru-ru (Du-ru-ru-ru-ru-ru-ru)
Du-ru-ru-ru-ru-ru-ru
Du-ru-ru-ru-ru
Du-ru-ru-ru-ru
Du-ru-ru-ru (Du-ru-ru-ru-ru-ru-ru)
Du-ru-ru-ru-ru-ru-ru (Du-ru-ru-ru-ru-ru)
Du-ru-ru-ru-ru
You make my life full of happiness
